In this week's Hacker Challenge, we asked you to hack your headphones. We received some great entries, but the winning hack shows us how to add a cable spool and Bluetooth adapter to your headphones.

Check out the description of the winning entry below and read about some of our other favorite entries.

Winner: Add a Cable Spool And Bluetooth Adapter to Your Headphones

Reader Balders2 gives us a three-in-one hack this week (see lead image). His cheap pair of knock-off Beats headphones broke at the hinge. Rather than give in, he looked around for something plastic (that is, TSA friendly) to fix them. He settled on plastic spoons, taping two spoons across each hinge—one facing up, one facing down. He also realized that he could use the spoons to spool the headphone cable, so he left them sticking out. Not satisfied with just fixing the hinges and having a new built-in cable spool, Balders2 also taped a binder clip to the phones so that he could attach his clipable Bluetooth adapter.

Okay, so it isn't the prettiest hack around. But fixing cheap, broken headphones and adding a built-in cable spool and wireless mic deserves some praise. How would you make it prettier? Let us know in the comments.

Honorable Mentions

We got a lot of great entries and we'd be remiss if we didn't share some of our favorites. Here are some of the entries that really impressed us.

Replace Your Built-In Headphone Cable With a Detachable Version

Sinan Midillili started with a set of Sennheiser HD595 headphones. Unhappy with the cable the headphones came with, Sinan decided to perform a little DIY magic. He replaced the built-in cable with a port that allows him to use a detachable cable. We could see this little hack being very useful. You could easily switch between cables of different lengths, depending on what you're doing, or just attach a better quality cable that whatever came with the headphones. It would also make it easier to replace a cable when it gets damaged—handy, since the cable is typically the most vulnerable part of headphones.

Double The Charge on Your Wireless Headphones

John Morales started with a Logitech G930 wireless headset. The micro USB charging port broke, preventing the battery from charging. John took it apart, thinking he could resolder the port but it was surface mounted and he didn't have much soldering experience.

Instead, John bought a DC power jack and a cellphone battery charger. With a bit of fancy rewiring, he was able to fix the charger as well as add a second battery in parallel, thus doubling the battery life for the headset. The only downside is that he now has to keep that charger (and, of course, the colors don't exactly match).

Make Your Headphones Wireless With a Clip And Some Velcro

Reader t0wer started with SRH-840 headphones. T0wer cut the adapter to fit in the headphones, attached the clip with Velcro, and then connected it with a 4" cable. Super simple and effective!

Turn Your Earbuds Into Binaural Microphones

Reader Dracogt turned a pair of earbuds into binaural microphones so that he could record holophonic sound. You can read a full description of how he did it on Instructables. In his own words:

They work fantastic and the illusion is pretty sweet to listen to. Super easy to make as well, i basically just replaced the speakers with microphones.

A big thanks to everyone who took the time to send us entries! Be sure to check back every week for a new challenge.
